Restless leg syndrome (RLS) occurs most often in middle-aged and older adults. The problem often runs in families. Diabetes, or nerve damage in the legs or feet may cause or worsen RLS. Women can get RLS while they are pregnant, but the problem usually goes away after the baby is born. Other problems linked to RLS include kidney failure, rheumatoid arthritis and anemia. Alcohol and tobacco can trigger or worsen RLS symptoms.
